CVE-2026-70642 · Severity: medium · CVSS 4.3 · Published 2026-11-12

ToolJet is a low-code application platform that allows users to build and manage applications within workspaces. An authenticated user can exploit an authorization flaw to read application metadata (version names, descriptions, status) from other workspaces by directly querying the app environments API endpoint. This information disclosure could aid an attacker in reconnaissance before launching a more targeted attack against other organizations on the platform.

## How to fix

- Fixed in 3.21.94

## Technical details

The /api/app-environments/init endpoint fails to verify that the editing_version_id parameter belongs to the caller's workspace, allowing authenticated users to retrieve app version metadata from arbitrary workspaces. The vulnerability affects multiple related endpoints (post-action, versions-by-environment, environments list) that similarly lack workspace scope validation. The fix (commit e5f387a) adds workspace-scoping checks before lookup operations and enforces required parameters.
